T 0 all whom it may concern:

Be it known that I, JAooB W. DUNHAM, a citizen of the United States,residing at \Vichita, in the county of Sedgwick and State of Kansas,have invented a new and useful Pen, of which the following is aspecification.

It is the object of this invention to provide a pen so constructed thatit will spread the ink in two stripes, one stripe being heavier than theother, means being provided whereby a blank line will exist in thatportion of the ink which is more heavily applied.

In the drawing :Figure l is a perspec tive showing the pen positionedfor writ ing, a portion of the handle of the pen bcing broken away; Fig.2 is an elevation of the pen; Fig. 3 is a fragmental longitudinalsection of the pen; and Fig. l is a transverse section of the bladeportion of the pen.

The pen herein disclosed comprises a handle 1 having a ferrule 2 andprovided at its lower end with a sleeve 3. Located within the sleeve 3is a pen holding member 4 having a slot 5.

The invention further includes a pair of blades 6 and 7, bent outwardlyintermediate their ends as indicated at 8 and 9, the upper ends 10 and11 of the blades being inserted into the slot 5 in the pen holdingmember 4, The lower ends 12 and 13 of the blades 6 and 7 are beveled toafford sharpened edges 14 and 15. The blade 7 is provided with end walls16 and 17 engaging the edges of the blade 6 to define a compartment. Theedges 14 and 15, adjacent one side of the pen are provided with teeth18. A partition 19 is secured to the blade 7 and extends through theblade 6, so that two diiferent colors of Specification of LettersPatent.

ink may be used in the pen. The lower edge of the partition 19 isbeveled as indicated at 20. One tooth of the series, indicatedspecifically by the numeral 21 is broadened, so as to leave a blankstripe in the writing, as clearly shown in Fig. 1. The teeth 18,,located upon both sides of the tooth 21, serve to accelerate the flow ofink upon both sides of the tooth 21 to draw the ink away from the tooth21 so that the latter will leave a blank stripe in the shading, ashereinbefore described, and as shown in Fig. 1.

Having thus described the invention, What is claimed is A pen comprisingconverging blades and a partition extending transversely of the bladesto define separate compartments, the marking edges of the blades beinunbroken upon one side of the partition, adjacent one compartment, andbeing provided with a series of teeth upon the other side of thepartition, adjacent the other compartment, the unbroken edges serving tospread the link lightly from the first compartment, and the teethserving to spread the ink thickly from the other compartment, anintermediate tooth of the series being broader than the other teeth, andthe other teeth serving to draw the ink from the broad tooth, wherebythe latter will leave a blank line in the more thickly spread portion ofthe ink.

In testimony that I claim the foregoing as my own, I have hereto ailixedmy signature in the presence of two witnesses.
